When is inhaler therapy recommended for COPD?

COPD can narrow the airways and make it harder to move air. A clinician may recommend a reliever inhaler for episodes of breathlessness, or a regular long-acting inhaler when symptoms continue between episodes. Some people need more than one inhaled medicine, with each one serving a different purpose. The choice depends on breathlessness, cough, mucus, previous flare-ups, other conditions, smoking exposure, and breathing-test results. Correct technique matters because medicine that stays in the mouth does not reach the lungs effectively.

Arrange a review if breathlessness limits walking, work or sleep, or if you are using a reliever more often than planned. Take every inhaler and spacer to the appointment so the technique and doses can be checked. Use maintenance inhalers on the prescribed schedule, even on a better day, and ask whether a spacer or a different device would make use easier. Do not start, stop or share an inhaler without advice. Avoid smoke and follow your written COPD action plan if you have one.

Seek urgent medical help for severe or rapidly worsening breathlessness, blue or grey lips, new confusion, fainting, chest pain, or inability to speak in full sentences. A sudden increase in coughing, wheezing or mucus, especially with fever or marked weakness, can signal a flare-up and needs prompt assessment.

Ask which inhaler is for immediate relief and which is for regular control, how long to try it, how to recognise side effects, and when your treatment should be reviewed.
